WebJan 31, 2024 · Efficient trajectory planning is thus required to extend the application scenarios. Hence, this paper proposes a “capacity collocation” scheme to improve the efficiency of trajectory optimization. First, the system dynamics is reformulated on the capacity domain, which transforms time-derivatives to capacity-derivatives. WebI haven't used shooting methods for trajectory optimization, but I have used collocation method so I will address it directly. The key trick to the collocation method is knowing how to compute the non-linear equality constraints using the dynamics of the problem.
